As a rule of thumb the low-end Apple products tend to come with shortcomings that the mid- and high-end product do not. While today's technology does not show off those differences, in 3 or 4 years, the technology and programming will have developed to the point where the 1.6 will be obsolete and the 1.8 will still have a few years left, simply by virtue orf minor design differences. So if you plan on having it for a while, it would probably be best to drop the extra couple hundred (if you can afford to.) Otherwise, if you plan on buying a new computer in a year or two, go ahead and get the 1.6.

I'm going with the 1.8 for the above mentioned reasons. I feel that over the next 3 to 5 years, the 1.8 has more growth potential. Also, if I'm going to have a box that big on my desk, I want it to have as much on the inside as it can hold.

Yeah, that makes a lot of sense. The PCI-X slots hadn't even entered my mind for some reason. The faster memory is probably worth it too. Now if we only had someone who could compare the Dual 2ghz with the 1.8...
